WALL-PAPER-TRIMMING MACHINE.

Specification of Letters Patent.

*atcnted Sept. 2, '1 ll 3.

Application filed November 13, 1912, Serial No. 731,123. Renewed July24, 1913. Serial No. 781,036.

To all whom, it may concern Be it known that I, \Vummu: Cm'on Armin, acitizen of the United States, residing at .Kolcomo, in the county ofHoward and State of Indiana, have invented new and useful ilmprovemcntsin \Vall-Paper- .[1.'innning hlachincs, of which the following is aspecification.

This invention relates generally to an improvement in "all papertrimmers and particularly to a simple means whereby the trimming of aroll of wall paper may be accurately and (BXLXClltlOHSly performed.

The main object. of the present invention is the provision of a holderin which the roll of wall paper may be quickly and accurately positionedand secured, and which when so secured may be readily subjected to theaction of the trimming knife to cut from the end of the roll thatportion only desired to be trimmed therefrom, the remaimler of th rollbeing protected against the knife and also secured in a manner to insurean even, sharp edge when trimmed.

The invention in its preferred form of details will be described in thefollmving speciIicatitm, reference being had to the accompanyingdrawings, in which Figure 1 is a perspective view of the im provedtrimmer showing a roll of wall paper therein. Fig. 2 is an end elevationof the same. Fig. 3 is a top plan view of the same. Fig. t is anelevation of the back sup port showing the inner face thereof.

teferring particularly to the accompanying drawings. my improvedtrinnner comprises a body made up of a base board 1 and end walls and 3,the former being termed the front support and the latter the rearsupport. The end walls are hingedly connected at t to the base 5, eachprovided with projecting tenons (i to fit in mortises 7 in the base whensaid parts are in operative position whereby to prevent undue strainupon the hinges in use and to accurately position the end walls withrespect to the base. Fastening means 8 of any appropriate type may beused to secure the end walls in proper position with respect to thebase. The front wall or support 2 is of greater width and height thanthe similar dimension of the rear wall or support 3, and the base board1 is correspondingly shaped being of a width corresponding to the widthof the front support of the forward end and reduced in width for thegreater port-ion of its length to correspond to the width of the rearsupport 2' at the end conncctcd to the latter.

The support 2 at a point above the base 1 formed with a transverselydisposed opening E) having upper and lower parallel walls 10. Theopening t) which fol-ins a slide-way opens through one edge of the frontsupport and is closed by a bar '11 bridging the walls ll), as shown. Theinner end or wall of the slide-way is rounded, as at 12, being at thispoint approximately semi-circular in shape and having a radius slightlyless than onc-half the height of the slide-way so that the terminals ofthe roundcd portion are spaced inwardly in both dircclions from theedges formed by the walls 2. A clamp block 13 is slidably mounted on theslidc-way the upper and lower cdg-cs of the block being preferablyformed with guide ribs to fit in corrcs ionding channels in the edges'10. An operating screw '14 provided with a handle 15 is threaded in thebar I1 and rotatably, though otherwise fixedly secured to the clampblock 1 and whereby in the operation of the handle the slide bloclc maybe adjusted to and from the semicircular edge 12 of the slide-way. Theinner edge of the clamp block is formed with a semi-circular depressionlti corresponding in all respects to the rounded edge 12. the partsbeing so positioned that when the slide block is at the limit of itsinward adjustment the rounded edges 1') and l.(' form an approximatelycircular opening.

Secured to the outer facc of the front support 2 is the fixed shear oredge for the cutter comprising a plate 17 secured to and spaced from thesurface of the forward wall of the front support by screws 'lti. Thatportion of the shear in which the screws are inserted may, if desired,be somewhat thicker than the reniainder so that the por tion above thescrews is spaced the appropriate distance from the surface of the frontsupport. This shear is formed in one edge with a rounded depressionl9.and said shear is secured upon the front support so that said roundeddepression accurately registers with the rounded depression 12 in thefront support.

The rear support is provided with a scmicircular block 20 secured to theinner face thereof and positioned to accurately and snugly receive theroll of paper and support the same in position. A retaining rod "llhaving a handle 22 and a stop collar 3 is designed to be passed throughan opening in the rear support, 3, said retaining rod be ing designed tobe passed through the opening in the rear support and through the cen-25 is provided including a rounded cutting blade 26 and a handle 27 thelatter being secured to the upper edge of the blade.

In use the roll of wall paper is arranged between the supports, and theend of the roll to be trimmed inserted in the slide-way and against therounded edge 12 thereof, being adjusted lengthwise with the outersurface of the front support of the guide so that the part to be trimmedfrom the rolls will be engaged by the blade; The handle 15 is thenoperated to adjust the clamp block to clamp the roll in place and theknife operated to trim the projecting edge of the roll. The roll is thenreversed and the opposite end trimmed, the block 20 being of a thickness to support the roll at the trimmed end in its adjustment in thetrimmer for trimming the second end.

When not in use the end supports may be folded down on the body so thatthe trimmer will occupy very little space. The shear cooperates with theknife to perform an efiective cutting operation and the roll when oncein position will be securely retained until the completed trimming ofone end is effected.

It is obvious that the hinges 4- are not essential to the operation ofthe device and that the parts may be formed with openings ing formedwith a slide-way having arounded inner edge, a clamp block movable inthe slide-way and having a rounded edge to cooperate with the roundededge of the slide way to secure the roll, and a shear secured to thesurface of the front support and overlying the rounded edge of theslide-way.

2. A wall paper trimmer includingabody, front and rear supportsconnected to the respective ends thereof, aholding block secured to theinner surface of the rear support, a removable retaining rod mounted insaid rear support, the front support being formed with a slide-Wayhaving a rounded inner edge, a clamp block movable in the slideway andhaving a rounded edge to cooperate with the rounded edge of the slidewayto secure the roll, and a shear secured to the surface of the frontsupport and overlying the rounded edge of the slide way, said shearhaving a rounded edge to register with the roundededge of the slide-way.

In testimony whereof I affix my signature in presence of two witnesses.
